In desperate need of help! Does anyone on here have experience with cyber security ?

Basically I am being bullied at work and it has now gotten to the point of them hacking my whatsapp on my phone. I think it maybe through the wifi connection at work but it seems like they have hacked my wifi at home and my phone as well.

I didn't do anything to them to deserve this (if I had I would've just accepted my fate) and I can't believe people would go so far to teach me a lesson. However, I dont feel safe and I need some tips in protecting myself or on how to sever the connection on the wifi.

Ps. One coworker has a Bachelor in Cyber Security.
